A full set of Lyra Polycolour pencils acts like a palette. Use light or white paper to maximize colour and create bright drawings. Coloured pencils adhere directly to paper without an underlying structure. They are made by binding stable pigments to a binding agent, producing a professional artistic tool. The round body, crafted from premium cedar wood certified by PEFC, has a dipped end to match the pencil's hue. Polycolor pencils feature a 3.7mm lead diameter for improved performance and contain permanent, UV-resistant pigments. They are waterproof and vivid, blending seamlessly for various shades and tones.
